Sustainable Process for the Extraction of Potassium from

To recover potassium from feldspar, a biowaste, i.e., eggshell, was used. The chief composition of eggshells is calcite. As it is a rich source of Ca, hence it is used with HCl to produce calcium chloride. Feldspar is an aluminosilicate mineral that bears potassium in the interstitial sites. To unlock the potassium from the interstitial sites, it was roasted with calcium chloride prepared by

Extraction of potassium from K-feldspar via the CaCl2

Sep 01, 2015· The extraction of potassium from K-feldspar via a calcium chloride calcination route was studied with a focus on the effects of the calcination atmosphere, calcination temperature and time, mass ratio of CaCl 2 to K-feldspar ore and particle size of the K-feldspar ore. The results demonstrated that a competing high-temperature hydrolysis reaction of calcium chloride with moisture in a damp

The Correlation of Roasting Conditions in Selective

The general formula of feldspars is XAl(1−2)Si(3−2)O(8), where X can alter as Na, K, and Ca. The feldspar group has nearly 20 recognized members but only two of them (sodium and potassium feldspars) are used commercially. When the Na2O content in feldspar is more than 7%, it is classified as sodium feldspar, and it is named as potassium

Feldspar Minerals Education Coalition

Hard-rock mining for feldspars is done by open-pit methods, either by the mine owner or by contractors. After the feldspar ore is drilled and blasted, secondary breakage is performed with a conventional drop ball. Ore is then loaded with a hydraulic shovel onto trucks and hauled to the crushing plant, which is adjacent to the flotation plant.
